Dyeing keratinic fibres, especially human hair

摘要

The present invention relates to the use of UV filters for substantially increasing the laundry fastness of dyes for keratinic fibres. The UV filters can be applied onto the fibres both directly with the colouring agent or in another step of this method. The agents obtained according to the present invention are associated with a combination of a water non-soluble UV filter, of a UV filter comprising a quaternary ammonium group and of a mono-, di- or oligosaccharide in order to substantially increase the laundry fastness of the dyes.
